When 0.340 mol of butane, C4H10, are burned with excess oxygen giving CO2 and H2O, how many moles of oxygen are consumed?

Answer 1

balance the equation. I bet you get four moles of CO2 and 5 moles of water for each mole of butane. If that is true, then you must use 4O2+5(1/2O2) of oxygen, or 6.5 moles O2 for each mole of butane. So you had .340moles, and that multiplied by 6.5 is ...
